Abstract
The utility model discloses a lift for a spare tyre. The lift for a spare tyre comprises a housing, a bearing shaft, bearings, a wire rope and a pulley. The bearing shaft is arranged in the housing; one end of the wire rope is fixedly arranged on the bearing shaft, and the other end is fixedly arranged at a certain position of the housing; the bottom end of the wire rope strides over the movable pulley; a spare tyre frame is connected with the movable pulley, the end of the bearing shaft possesses a crank; two ends of the bearing shaft are provided with the bearings; and the bearing shaft possesses a back stop device. According to the utility model, a sprocket wheel chain assembly is replaced by the pulley assembly, defects in the prior art are overcome, the wire rope is not easy to fracture, rotate or clamp, the structure is simple, a fault is not easy to happen, and the lift for a spare tyre is economic and practical.
Description
Technical field:
The utility model relates to the stepney lifter.
Background technology:
The full-sized car tire is huge, leans on manpower can't move spare tyre, generally is furnished with the spare tyre lifter with car.The spare tyre lifter of prior art is the chain extending type; Basic structure comprises hanging holder set, sprocket chain bar assembly, and sprocket wheel is installed on the load-bearing axle, rotates rocking arm and drives the rotation of load-bearing axle; Sprocket wheel drives the chain up-and-down movement, rises or falls thereby will be fixed on the terminal tire of chain.Its technological deficiency is: 1. chain spins easily, blocks and end in lifting process.2. driving gear damages easily, and gear can't keep in repair after damaging, and can only change, and use cost is high; 3. chain ruptures easily.4. the load-bearing axle does not have bearing, and friction force is big, and the up-down resistance is big, and operation labor intensity is high.
The utility model content:
The purpose of the utility model provides a kind of simple in structure, the spare tyre lifter that fault is few.
The utility model comprises housing, load-bearing axle, bearing, steel rope, pulley; The load-bearing axle mounting is in housing; Steel rope one end is fixed on the load-bearing bearing, and the other end is fixed on a certain position of housing; The steel rope bottom strides across movable pulley; Spare tyre holder and movable pulley link, and the load-bearing shaft end has crank.
Said load-bearing axle two ends are provided with bearing.
Said load-bearing axle has non-return device.
The utility model, the design of the movable pulley assembly, wire rope end fixed to the housing and the other end fixed on the bearing shaft, by rotating the crank shaft bearing, the bearing shaft rope Chan around or released, so that the movable pulley raised or lowered, to achieve Lift the spare wheel holder.The utility model has replaced the sprocket chain bar assembly with pulley assembly, has overcome the defective of prior art, and steel rope is easy fracture not, does not spin, and does not block and ends.Steel rope strides across pulley, has increased the weight capacity of steel rope.Design bearing at load-bearing axle two ends, reduced friction force.The non-return device of load-bearing axle can stop the reversing of load-bearing axle.The utility model is simple in structure, and easy fault is not economical and practical.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further.
Like accompanying drawing, the spare tyre lifter comprises housing 1, load-bearing axle 2, bearing 3, steel rope 4, movable pulley 5, spare tyre holder 6, crank 7.
Load-bearing axle 2 is located in the housing 1, and steel rope 4 one ends are fixed on certain of housing, and the other end is fixed on the load-bearing axle 2, and load-bearing axle 2 two ends have bearing 3.Steel rope 4 bottoms stride across a movable pulley 5, and movable pulley and spare tyre holder 6 fix.Load-bearing axle 2 ends have crank 7.
The load-bearing axle has non-return device 8, and non-return device adopts gear anti kickback attachment of the prior art to get final product.Non-return device comprises a gear and a check pawl that prevents said gear reversing that is fixed on the load-bearing axle in the accompanying drawing.
Spare tire mounted on the spare wheel frame 6, the lifting operation, the Turning the handle 7, the bearing shaft 2 is rotated, the rope 4 Chan around the bearing shaft 2, the spare wheel (5) movable frame 6 with improved load-bearing shaft return device 8 prevents bearing axis 2 reversed.In the time of need falling spare tyre holder, stir the check pawl, away from anti-reverse gear, backward rotation crank 7,2 counter-rotatings of load-bearing axle, steel rope 4 discharges from load-bearing axle 2, and spare tyre holder 6 descends with movable pulley.
Load-bearing axle 2 two ends are established bearing 3 and can be reduced friction.
Claims (3)
1. spare tyre lifter, it is characterized in that: it comprises housing, load-bearing axle, bearing, steel rope, pulley; The load-bearing axle mounting is in housing; Steel rope one end is fixed on the load-bearing bearing, and the other end is fixed on a certain position of housing; The steel rope bottom strides across movable pulley; Spare tyre holder and movable pulley link, and the load-bearing shaft end has crank.
2. spare tyre lifter as claimed in claim 1 is characterized in that: said load-bearing axle two ends are provided with bearing.
